The I²C interface lets the host set the charge current and monitor fault conditions, including over-temperature and over-voltage protection. The 3 A maximum charge current supports fast charging of single-cell Li-Ion packs in the 2–4 Ah range, typical for handheld terminals, medical devices, and portable instruments. The I²C bus allows the system microcontroller to adjust the charge current dynamically, terminate charging at the correct voltage, and read fault flags — eliminating the need for external resistor dividers or logic pins. The 3.5 V battery pack voltage is the regulation target for the single-cell Li-Ion chemistry. The constant-current / constant-voltage profile is handled internally; the host only needs to set the current via I²C. ## Obsolete — sourcing through independent distribution The BQ24261RGER carries an obsolete lifecycle status.","metaTitle":"BQ24261RGER Li-Ion Charger IC, 3A I²C, 24-VQFN, Obsolete","metaDescription":"Texas Instruments BQ24261RGER single-cell Li-Ion charger with I²C interface, 3A max charge current, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24261","Battery Pack Voltage":"3.5V","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"13.2V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$105.7000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for BQ24261RGER?","answer":"No official direct replacement or pin-compatible upgrade is recorded for the BQ24261RGER.
